Forward Simulation Results of CSAMT Data on Considering IP Effect

The CSAMT responses of geoelectric media are actually the accumulation of electromagnetic response and induced polarization under the stimulation of controlled source. The resistivity is dealt as a parameter which is scarcely related to the frequency when we proceed the forward and inversion with field data. Due to the induced polarization of underground layers, however, the resistivity of polarized layers is complex number relating to the frequencies and using only resistivity will lead an inaccurate result. This paper provides a primary trial in solving this problem that not only the current research situation of basic theory of IP in recent years, but also a few of preliminary modeling results are presented.
